Edmond Dantès;47538469 said:Even Tolkien made that mistake sometimes. In fact Dwarves was wrong altogether, but Tolkien still chose that way of spelling it.
I remember reading the Annotated Hobbit for the first time and being introduced to the word "Dwarrows". I though it was amusing that Tolkien intentionally used Dwarves because, essentially, he liked it better (and it matched Elf/Elves). I suppose as a consolation prize we got "Dwarrowdelf"
